yeah if you click on the photo it opens up more info and in the FAQ they say: 'Generally, we recommend that you replace your Lily Cup™ every 12 months, but if cared for properly, it is up to your discretion to determine when to replace it.'

So it doesn't need replacing, but we'd quite like the extra money....

they also say: 'Menstrual flow is not a determining factor when selecting your size.' yeah right.
